Question

I’m trying to execute a Ruby script that uses parameters passed to it from a Ruby on Rails form.

This is a snippet from my from:

<%= form_for(@test, :html => {:name => "test", :id => "test"}) do |f| %>
    <div class="field", id="configure_device">
        <%= f.label  "Label1" %>
        <%= f.text_field :Form_Param1 %>
        <%= f.label "Label2" %>
        <%= f.text_field :Form_Param2 %>
        <%= f.label "Label3" %>
        <%= f.text_field :Form_Param3 %>

<… more text_fields here …>

    </div>
    <div class="actions">
        <%= button_to 'Apply Configs', :remote=>"true" %>
    </div>
<% end %>

My Ruby script’s structure is as follows:

def apply_configs (param1, param2, param3, ..., etc.)
    <... ruby code that executes based on the values passed in param1, param2, param3 ...>
end

I tested this Ruby script separately and it works just fine if it receives the right input parameters param1, param2, param3, ..,, etc.

Te question is how can I execute this Ruby script when the “Apply Configs” button is clicked and how can I pass to it parameters Form_Param1, Form_Param2, Form_Param3, …, etc. to be mapped to param1, param2, param3, …, etc.?

Answer 1

You have to receive it from params , there are no need of arguments

def apply_configs
   form_param1 = params[:test][:Form_Param1]
   form_param2 = params[:test][:Form_Param2]

   // similarly

    <... ruby code that executes based on the values passed in param1, param2, param3 ...>
end
